Application filed January 13, 1909.

To all whom it may concern:

it known that I, RALPH C. Snraroun, a citizen of the United States, andresiding at Larchmont, in the county of .Vescchester and State of NewYork, have invented certain new and useful Improvements in FoldingMachines, of which the following is a specitication.

The invention relates to folding machines and in certain of its aspectsto rotary folding machines, although in certain other aspects theinvention may be applicable to other kinds of folding machines.

Objects of the invention are to provide for handling a sheet duringfolding to avoid all creasing, rubbing, smutting, or other injuriousaction due to constraint by or contact with the machine parts and at thesame time to handle and position the sheet for easy delivery and withthe two sides lightly but nicely laid together; to provide for suchaction and handling of the sheets while running at high speeds, so as tosecure a. product large in quantity while excellent in quality; toprovide for rapid and at the same time exact and uniform folding of thesheets; to secure various products, or various ways of folding, whilealso realizing the advantages enumerated; to provide mechanisms whicheffect the various objects coincidently and harmoniously; to provideparticular mechanisms within a folding machine for effecting thesefunctions; to provide a machine of simple, strong and economical designand construction, and wherein the parts are easy of access andregulation. These and other objects of invention will in part be obviousand ill in part appear hereinafter.

The invention consists in the novel parts, arrangements, constructions,combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and forming a part hereof,illustrate one embodiment of the invention, the same serving inconnection with the description herein to explain the principles of thein vention.

Of the drawings: Figure 1 is a vertical section on the line AB of Fig.2; Fig. 2 is an end. elevation looking to the right in Fig. 1; 8 is aview corresponding to Fig. 1, partly diagrammatic, and showing the ma-Specifioation of Letters Patent.

l chine arranged for collecting and folding; Figs. i and 5 show detailsof the gathering mechanism on an enlarged scale A ig. 6 is a view,partly diagrammatic, showing various positions of the folding jawsduring their cycle of movement; Figs. 7 and 8 show details ofconstruction of the folding blade on an enlarged scale; and Figs. 9, l0and 11 show the folding blade and folding jaws in various positions. 3

Referring to the accompanying drawings, illustrating by way of examplean embodiment of the invention, suitable means are provided forsupplying sheets to the machine. Said means-may be of any suitable orconvenient form, and may supply the sheets from any suitable source,such as a printing press or other machine. The form of such means shownherein comprises devices for leading a web 1 into the machine, such astapes 2 traveling about rolls 3.. Guide bars a and 5 are shown supportedupon rods 6 to constitute a throat for fur ther guiding the end of theweb as itfeeds downwardly as successive sheets are cut off. Any suitableform of means for severing the web into sheets may be provided, and theform thereof herein shown comprises cutting cylinders 7 and 8, whichneed not be described in detail.

The invention in one of its aspects provides a pair of folding jawsmovably mounted upon a traveling carrier, by which the sheet is carriedfree from contact with or constraint by the other machine parts, so asto avoid the disavantages specified, and in connection with such aconstruction a control of the movement of the jaws upon the carrierbetween the point of folding in and the pointof delivery such as willbring the sheet nicely together by atmospheric action and dispose orposition it most advantageously for transfer to the delivery devices,and to permit of such action at relatively high speed.

More particularly, and as exemplified in the illustrated form of suchmeans, the fold ing jaws are caused to move relatively to their carrierduring the folding in of the sheet and to be at rest relatively theretofor a period just prior to the release of the sheet. By one feature ofthe invention a folding blade is provided swinging about a center,

and cooperating therewith a pair of folding jaws swinging about a centerupon their.

carrier, which also swings about a center, and in connection therewithmeans for permitting and preventing the movement of the folding jawsabout their own center and relatively to their carrier. By permittingthe complete set of movements a very nice and accurate, but neverthelessrapid, folding in of the sheets into the jaws is eifected, whilepreventing the motion of the jaws about their center and with respect totheir carrier for a period just prior to the release and transfer of thefolded sheet to the delivery device, the same excellence and rapidity ofoperation of that mechanism is maintained, while a most desirableatmospheric action for effecting the drying, folding and positioning ofthe sheet is secured.

En the form of means herein illustrated carrier arms 9 are shown fixedto a rotating shaft 10. Mounted in said arms 9 away from the shaft 10,and preferably near the.

extremity of said arms, are shown crank shafts 11 carrying crank arms12. Between the crank arms 12, and preferably fixed thereto is shown ajaw 13; Cooperating with said jaw 13 is a movable jaw 14L shown mountedupon the shaft 15 carried between the crank arms 12. The shaft 10 isrotated by suitable means, which need not be described in detail, tomove the carrier 9 in an endless path, which in the present embodimentis likewise circular. So far as concerns certain features of theinvention, how ever, the travel of the carrier might be along some pathof different form. Means are also provided for moving the pair of jawsrelatively to their carrier, and in the pres ent embodiment the jawsmove in an endless and likewise circular path upon the carrier. The formof such means shown herein comprises a pinion 16 meshing with an idler17 which in turn is in mesh with a gear 18.

The form of means for controlling the movement of the pair of foldingjaws relatively to their carrier shown in the present embodimentcomprises devices acting upon the gear 18 to cause it to move with thecarrier or to hold it from such movement, and to perform said functionin harmony with the positions and functions of the other mechanisms.Accordingly the gear 18 is shown integral with a gear 19, and as beingloosely sleeved upon a suitable bushing fixed to the frame 20 of themachine and as held in position by a bracket 21. Meshing with the gear19 is shown a sector gear 22 fixed to the bentlever 23. The free end ofthe lever 23 is shown in operative relation, through the roll 24, with asuitable groove or box cam 25 carried on the shaft 26.

A suitable folding blade 27 is shown mounted on a suitable carrier, suchas the cylinder 28, to cooperate with the folding in comprises acylinder 29 having grippers 30 for taking the sheets from the foldingjaws. The construction and action of the salt. delivery devices willlikewise be more fully described in connection with another feature ofthe invention.

Suitable means for opening and closing the folding jaws at the properpoints are provided, and so far as the present invention is concernedthey may be of any suitable or convenient form. As shown herein the awsare normally held closed under the impulsion of springs 31, and areopened by the action of came 32 on rolls 33 carried by arms The cams 32are carried on levers 35 which are in turn controlled by suitable cams36. The general features of said mechanism, as well as the generalconstruction of the folding jaws and their mounting upon the carrier,are substantially similar to the corresponding mechanism shown in myPatent N umber 908,157 of December 29, 1908, and detailed descriptionthereof is unnecessary.

In the present embodiment a plurality of folding jaws and carriers areprovided, all ceoperating with a single folding blade and a singledelivery mechanism, or either of these as desired. Two carriers and twopairs of folding jaws are accordingly shown in the present embodiment,the second carrier being indicated generally by the reference numeral 37and the pair of folding jaws by the numeral 38. These may be used tofold singly, when desired, the folding blade carrier revolving twice foreach revolution of the shaft 10.

According to one aspect of the invention,

means are provided for collecting and'folding together a plurality ofsheets, and in the form of such means shownherein the cylinder 28 may beused as a collecting cylinder. And in such case, with the illustratedmechanism, one pair of folding jaws is rendered inoperative. Anysuitable form of neans for doing this may be provided, and shown herein(see Fig. 3) the crank shaft 39 is shown removable from the carrier 37by unbolting the bearing caps a0. The connecting gears may also beremoved if desired. Suitable sheet taking means may be provided on thecylinder 28 and grippers 59 are shown for this purpose. Said grippersmay be set to take a sheet at each rotation of the cylinder, or after aplurality of rotations, or may be rendered entirely inoperative may bedesired. No specific form of gripper controlling means is shown ordescribed, as various forms of such means are old in the art.

Suitable means for directing the sheet into the bite of the grippers areprovided and ilso means for rendering said n'ieans opera. ive orinoperative are likewise provided. The form of such means herein showncomprises tucking blades carried upon a shaft it supported on arms i7fixed to the shaft 10. lprings in are shown acti to hold the tuckingblades in a retracted position with the r supporting arm against a stopl9. Fined to the shaft -iii is shown an arm 50 carry a truck roll 51. Lisuit-able cam shape is provided and this may be mounted so as to benuwable into and out of the path of roll Ill, as by bolt-and-slotconnections 52-3. lllien the cam in position, the tut *ing fingers towill act to press end of the sheet against the surface of cylinder 28 soas to cause the grippers *i) to gr p the end of the sheet. it will beunderstood that this feature may be used either when folding single, orwhen collecting and folding, or wen folding single it may be keptinoperative, and the end of the sheet n be allowed to run down freely.li hen folding double froi'n a plurality of webs the said feature may beused or not as desired. However, by causing a single pair of foldingjaws or a plurality thereof to co operate with the said cylinder, andwith suitable operation of the gripping devices, a single or multifoldproduct relatively to the nui'nber of webs fed in may be secured.According to one feature of the invention means for taking the foldedsheets from the folding are provided traveling in the same absolutedirection but at rest, or traveling in the opposite direction relativelyto the traveling folding jaws. The delivery de *iees showrhereincomprise the cylinder 29 provided with suitable sheet taking devices,such as the grippers These may coaet with the folding jaws in anysuitable manner to engage the sheet along the folded edge. and if(lured. this may be done as illustrated and described in my patenthereinbefore referred to. in the present embodiment. the cylini'ler hasa surface or peripheral s eed less than that of the linear speed of thefolding jaws. This is conniently eii'ected by giving the carrier andfolding jaws and the delivery cylint er the same angular velocity. thedifference in radius then giving the desired relation. The cylinder isalso shown provided with additional grippers 5% which may be set inharmony with either a single or inultifold operation of the foldingdevices, both sets of grippers acting when both sets of folding jaws areoperating. Suitable means for receiving the folded sheets from thedelivery cylinder and conveying them away are pro rided, and the formthereof herein shown comprises a traveling pocket conveyer into whichthe sheets are directed f om the cylinder 29 by suitable strippingfingers 56.

The, invention in certain of its features contemplates means foretl'ecting an ac curate and uniform folding of the sheet while runningat high speed without any plucking, straining, or harmful drawing of thesheet, and in carrying out this feature of the invention a form of meanshas been provided whereby the blade passes within the jaws without fricion or sliding of these parts upon each other or upon the interposedsheet, and providing for a sudden and quick closing of the aws upon thesheet and blade. and according to one feature a movement of the bladewith a movable aw toward a fixed jaw, and then a compensating movementof the blade during the combined traveling and withdrawing motion of theclosed aws car rying the sheet. The form of such means shown herein, anaddition to the genera arnigement and construction of parts alrez'idydescribed, comprises a spring mounting for the tucking blade 27. Saidblade is also shown mounted in the block (50, which is adjustable uponits cylinder. The blade 97 may be substantially rigid in itself, and isshown herein mounted in a rod (51 rotatably carried bythe block (30. Theblock (50 is shown recessed at 63 so as to permit the blade 2? to movewhen engaged by the closing movable aw member, and also when for aninstant it is gripped by the closed jaw, the sprin s then acting torestore it to its initial position. The cylinder 28 is shown with aflattened or scarfed portion Set which will permit movement of the sheetduring the entry of the tucking blade with the sheet into the foldingjaws without causing any plucking of the sheet from beneani the gripperor of any undue straining upon the web.

The manner of operation of the herein described mechanism issubstantially as fol lows: As the web 1 is fed downwardly it will passalong between the guides d and 5 and may be either taken up by thegripper upon the cylinder 98 or allowed to run free. as desired. Thefolding jaws and the folding blade will then cooperate to make a fold inthe paper, and about the same instant the cylinders T and S will severthe sheet from the web, the free on d of the web then feeding down forthe next operation. it will, be seen that the folding blade 2'? isswinging around the center of its carrier during the folding in, whilethe pair of folding jaws is swinging about its own center of rotation onits swinging carrier. Thus the folding blade and the pair of aws areeach traveling on the same side of its own center during the folding in.

in greater particularitv in the present 1* embodiment anc rereirmg to llgs. 1, o and 6, the folding blade 27 1s swinging about the center ofthe cylinder 28. and at the left of said center; the pair of folding aws13,

' folding blade 27.

1 1-, carried by the crank arms 12, are swinging about the bearing ofsaid crank arms 12 in or near the ends of the carrier arms 9. Said crankarms 12 are at the left of their hearings in said figures of thedrawings. Thus it will be seen that the pair of jaws and the blade areswinging about the same sides of their respective centers during thefolding in of the sheet.

By reference to Fig. 6 a plurality of positions of the folding jaws willbe seen. In the present instance the gears 16 and 18 are in the ratio oftwo to one, thus giving twoabsolute rotations of the jaws upon thecarrier during each cycle of operation, but owing to the movement of thecarrier in the opposite direction giving but one revolution of the jawsrelatively to the carrier for each revolution of the carrier. If thegear 18 be moved during the travel of the carrier 9, the movement of thefolding jaws relatively to the carrier will be modified accordingly, andif during a cycle of movement of the carrier, that is, during onerevolution, the gear 18 is moved in one direction and then moved backagain an equal distance in the opposite direction, it will be seen thatthe movement of the aws relatively to their carrier will beintermittent, or varied, but that the aws will be in the same positionat the end as at the beginning of the cycle of revolution.

In Fig. 6 the folding jaws are shown at (a) having the sheet foldedthereinto by the At (Z2) the jaws are shown pointing backwardly, thatis, with the folded edge engaged by the jaws in advance. At this pointthe geared sector 22 is given movement by the cam 25 to compensate forthe movement of the carrier 9. Thus the folded sheet is carried freelythrough the atmosphere without further rotation but with a movement oftranslation, which acts to bring the two parts of the sheet together.During this time the sheet is delivered to the delivery cylinder 29. Atabout the position (a) the sector 22 receives movement in the oppositedirection, and the jaws now receive an accelerated rotation due to theresultant of the movement of the carrier arms 9 in one direction and ofthe gear 18 in the opposite direction. Various positions of the awsduring such movement are shown approximately from to (g) respectively.At the position (g) or near thereto, the gear 18 comes to rest and aless rapid movement is imparted to the folding jaws about their centerduring the folding in operation. The cycle of movements described isthen re peated with succeeding sheets.

To effect the multifold operation, which with the present embodimentconsists in a double folding, one pair of folding jaws is renderedinoperative, and this may be effected by removing the jaws by unboltingthe bearing cap 40 (see Fig. The cam 52 is now adjusted to operate thetucking blade do. The gripper 59 takes the sheet, as shown in 5, thesheet passing around the cylinder, and as the folding jaws 38 areremoved or otherwise inoperative, there is no folding action and thegrippers carry the sheet around for the subsequent revolution. The endof tne web 1 is again run down-' wardly and the tucking blade 15 pressesit against the cylinder 28, already carrying the previous sheet, asshown in Fig. The operative folding jaws 13 and let now fold theassociated sheets over the folding blade 27, the gripper 5.) opening torelease said sheets. The deli-v ry action may be substantially the samein both cases excepting that but one set of grippers on the deliverycylinder are used for the double folding instead of both. The action ofthe specific form of delivery cylinder has already been explained inconnection with the previous description.

In Figs. 9, 10 and 11 the action of the folding jaws and folding bladeare shown in detail, it being understood that said showing is more orless diagraimnatic. The swinging of the cylinder 28 and of the carrier 9about their centers causes the blade to move inwardly with the sheetbetween the separated jaws 13 and 14:. Said parts are so proportionedand positioned that the jaws do not bind on the blade but a free spaceis left therebetween, as shown in Fig. 9. The moving jaw 1 1 thenreceives the sudden closing movement toward the fixed jaw 13, and theblade 27 moves therewith against its springs. At Or about this instantthe receding movement begins and the sheet is carried off the blade bythe jaws, the blade at the same time being free to move in the oppositedirection with the slight angular advance of the cylinder 28 and arms 9during this time. The fiat portion 64; upon the cylinder will act togive the necessary movement of the paper between the grippers 59 and theblade 0 27 to prevent any plucking at the gripper or slipping orscraping over the blade. In Fig.

11 the folding jaws are shown moving away with the sheet, the foldingblade having sprung back to its original position. It will be understoodthat the action of the said parts is practically the same, so far asthis feature is concerned, whether the sheets be taken around thecylinder 28 or not.

From all the foregoing it will be understood that the mechanism shownand described embodies the principles of the invention, and that itrealizes the objects of invention and the advantages herein set forth,together with other objects and advantages.

The invention, in its broader aspects, is not limited to the particularconstructions shown, nor to any particular constructions by which it hasbeen or may be carried into effect, as many changes may be made in theconstruction without departing from the main principles of the inventionand without sacrificing its chief advantages.
